Title: The Innovations of Henry K Tom
Introduction
Henry K Tom is a notable inventor based in La Honda, California. He has made significant contributions to the field of immunoassays, holding a total of 5 patents. His work has advanced the methodologies used in detecting analytes in various samples.
Latest Patents
One of his latest patents is titled "Assay having improved dose response curve." This invention involves an assay designed to determine the presence of a threshold concentration of an analyte in a sample. The process includes reacting the sample with an amount of anti-analyte to reduce the free analyte to a marginally detectable concentration. The sample is then contacted with anti-analyte immobilized on a test region, allowing for the detection of the residual free analyte through various techniques. This method enhances the sensitivity of the assay by employing limited amounts of anti-analyte on the solid phase.
Another significant patent is the "Method of sample transfer using a filter applicator." This invention features a sample applicator that includes a tube with a filter matrix at one end. The sample is drawn into the tube, filtered as it enters, and again filtered upon discharge. This dual filtration process improves assay performance by removing particulates from the liquid sample. Additionally, the applicator may contain a reagent within a permeable matrix, which simplifies the assay process by reducing the number of steps required.
